New licence model for the first time with Windows Server 2016 Standard and DataCenter
In previous versions, both the Standard and the DataCenter licence were valid for two physical CPUs.
In the new licence model, licensing has changed from a per-CPU model to a per-core model. It is assumed that a server will have at least 8 cores per processor and at least two processors, i.e. a total of 16 cores.
16 cores is therefore the minimum per server; at least 8 cores must be licensed per CPU. This means the licensing costs for servers with up to 4 processors and up to 8 cores remain identical.
Additional licences must be purchased for better-equipped servers. The additional licences are available in 2-core addons. In addition, user/device CALs must be purchased. You can buy these from us cheaply as well.
